Title: Ttl-to-ecl input translator/driver circuit
Inventor: KHAN AURANGZEB K
IPC: H03K19/018
Filed: 1988-11-18
Granted: 1991-12-03
Abstract: TTL-TO-ECL INPUT TRANSLATOR/DRIVER CIRCUIT                 ABSTRACT OF THE INVENTION The present invention provides a high speed low power electrical circuit for converting true TTL level signals to true ECL level signals.  The circuit only has a single buffer delay with some small addi-tional delay due to an input emitter follower stage. The circuit includes a clamped, switched emitter fol-lower which acts as a level shifting comparator; a self-centering reference threshold translator; a clamped level shifted input translator; and, an ECL Buffer Driver. The circuit also includes a TTL reference and an ECL reference which are tied together.  If the TTL reference level shifts slightly due to temperature changes, supply voltage shifts or other factors, the ECL voltage refer-ence will automatically shift by an appropriate per-centage to compensate for the original shift in the TTL reference.

Abstract: "TRANSPONDER FREQUENCY OFFSET COMPENSATION WITH     RECURRENTLY ASSIGNED UNIQUE WORDS"               ABSTRACT OF THE DISCLOSURE In a satellite communications system) satellite channels are divided into groups of successively adjacent channels which are covered by a range of frequency drifts caused by a satellite transponder and the channels of each group are assigned unique words of different bit patterns. Modulation systems of an earth station are associated respectively with demodulation systems of distant earth station via the respective satellite channels. A unique word is transmitted from each modulation system together with an information signal and received by an associated demodulation system of the distant earth station. A variable frequency carrier is synthesized in the demodulation system to demodulate the received signal to recover the information signal and the unique word. The recovered unique word is used to establish the frame start timing and the variable frequency carrier is controlled in response to the unique word to tune in the demodulation system to the desired satellite channel.

Granted: 1992-08-11
Abstract: ABSTRACT     A shielded safety syringe comprising a cylindrical outer protective sleeve, a cylindrical inner needle carrier movable axially through the outer sleeve, and a double-ended hypodermic needle retained at a distal end of the needle carrier and movable with the carrier through the sleeve.  A movement of the inner needle carrier through the outer protective sleeve correspondingly causes the needle to be relocated from an axially extended position, at which to make a veni puncture through a patient's tissue, to a retracted position, at which the needle is completely surrounded and shielded by the outer sleeve to permit a safe handling and disposal of the syringe.  When the needle is located in the retracted position, a portion of the needle carrier may be rotated and the needle thereby canted toward the outer sleeve to prevent both access to the needle and the return of the needle to the axially extended position, whereby to avoid an accidental needle strike and the spread of a contagious and, possibly life threatening, disease.

Abstract: ABSTRACT OF THE DISCLOSURE       Methods of controlling  the wavelength and output power of a laser  device  with  two  intracavity  etalons are  disclosed,  together with a wavelength monitor capable of detecting sidebands. A method is characterized by the usage of hot/cold parameter K which takes two values 0 and 1 indicating the cold and hot state of the device, respectively. The parameter K, which is reset to 0 at the start, is set  to  1  when  the  laser  beam  is stabilized;  it  is  reset  to  0, whenever  the  lasing pause  exceeds a predetermined  time  length. A preparatory starting steps are performed or omitted at the start, depending on the value of K. Another method is characterized by the adjustment of the  intracavity etalons during the  lasing pauses,  in accordance with exponential  functions with thermal  time constants.       The sideband detecting wavelength monitor comprises a sigle etalon whose free spectral  region FSRm  is selected with respect to that, FSRz, of the fine tuning intracavity etalon in such a manner that the  interference fringes  of  the  sidebands  formed  by  the  monitor etalon are distinct from each other and from those of the central wavelength  .lambda.o. Namely, when  i  is  the  integer which  is associated with a sideband wavelength .lambda.s via the equation: .lambda.s = .lambda.o + i x FSRz, the  free spectral  regions  FSRz  and FSRm  are selected  in such a manner that the apparent wavelength differences: R = i?FSRz + j?FSRm between the central wavelength .lambda.o and the sideband wavelengths .lambda.s, wherein j is an integer which minimizes the value of R for each i, are different from zero and from each other.

Abstract: Sheet material (30) is cut into rectangular segments (35). The segments are then moved parallel to their cut edges rapidly away from the cutting station into a slower operating first sewing station (40) where elastic bands are sewn to the cut head and foot edge portions of the segment. The rapidly moving trailing portion of the segment (35) of sheet material is temporarily accumulated at the accumulation station (39) and progressively fed at a lower rate from the accumulation station to the first sewing station. The head and foot edge portions are folded into overlying relationship with respect the main body portion by passing the main body portion through a U-shaped turn and at the same time passing the head and foot edge portions through a pair of 90 degree turns. Sewing machines are moved first inwardly and then outwardly across the folded edge portions of the segment, thus forming the sewn line of chain stitching at the corners of the bed sheet.
